BELT-SHIPPER.

SPECIFICATION forming part of Letters Patent No. 247,131, dated september 1c, 1881.

Applicationled Augnst15,1881. (No model.)

To all whom .it may concern:

Be it known that I, STEPHEN STRUNZ, a citizen of the United States, residing at Pittsburg, inthe county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Belt-Shippers, of which the following is a specification.

This invention relates to a device that is especially designed to be employed in connection with theV belt-shipper secured to me by Letters Patent of theUnited States numbered 244,336, and dated July 12,1881,the present object being to provide a device by means of which at any given time it can be automatically actuated by some machine with which it will be connected, so as to cause the operation of the belt-shipper, thereby effecting the shipping of the belt from the i'ast to the loose pulley and checking the transmission of motion to the said machine, which has primarily actuated the devicewhich constitutes the chara cteristic feature of my invention.

Inthe annexed drawings7 which illustrate rnyinvention,Figure1 is a side elevation illustrating the same as applied to a baling-press, and also illustrating the belt-shipper which constitutes the subjectof the aforesaid patent. Fig. 2 is a perspective view of my device detached. Fig. l3 shows the slide-bar, and Fig. 4 illustrates a modified form of locking-lever. Fig. 5 is a modication of the locking device.

The belt-shipper consists, essentially, of a ointed bar composed of the three hinged sections A, B, and C, the section A, which slides through suitable guides, being provided with a bail passing around a belt, D, and being hinged to the central section, B, by a hinge on their top sides, the said central section being hinged to the remaining end section by a hinge on their under sides, and the said end section being pivoted at its outer end to a suitable support, so that when the requisite degree ot' tension is exerted upon the cord E, which is secured to the central section of the jointed bar, the sections B and C will be lifted at their meeting ends, as indicated in dotted lines, thereby retracting the sliding` section A and shifting the belt from the loose pulleyF to the fast pulley G, in order to transmit motion to the shaft upon which the said pulleys are mounted. 1n order, now,to secure this cord so as to maintain thejointed barin this position, and also so as to automatically release the cord at the proper moment, so as to allow the hinged bar to straighten out and shift the belt from the fast to the loose pulley, in order to check the transmission of motion to the shaft, and

consequently stop the machine to which mo tion may be transmitted from a pulley upon said shaft by a belt,'H, I attach to the cord depending from one of the pulleys, I, over which it passes, a slide-bar, K, formed with a notch, k, and arranged to slide along a suitable way in a casing, L, and I engage in said notch ot' the slide-bar the beveled end of a locking-bolt, M, arranged to slide within said casing. This casing will be attached to some suitable machinesuch as a baling or other press, a lathe or other machinewhere it has heretoiore been found necessary to have an attendant to stop it at certain moments during its operation.

In order to release the bolt from the slidebar, so as to allow the same to be raised by the tension which the weight of the two raised hin ged sections of the shipper will exert thereon, I provide the leverN, thatis pivoted to the case and formed with a short arm, n, which is received in a notchm, in the bolt. The long arm of this lever extends out through the casing, and has suflicient vertical play to admit of the bolt beingdrawn back and released from the vertical slide-bar when the said long arm of the bolt-operating lever is raised for such purpose. As soon as the bolt has been thus released the slide-bar will be drawn up by the cord, and hence the jointed bar ot' the shipper will be allowed to straighten out and ship the belt from the fast to the loose pulley. To ship the belt back again it will be only necessary to draw down the notched slide-bar attached to the cord and to operate the lever so as to slide the bolt forward and cause it to engage the notch of the said bar. Now, it will be evident that this lever can be raised at a given time by a variety of classes of machines.

As herein shown, I have illustrated an ordi nary press provided with an indicating-rod, P, that will be raised with the follower of the press. This rod can be set with reference to a graduated scale, Q, upon the frame of the press, and the long arm ot' the bolt-operating lever arranged so that as the rod rises the lef ICO this may be found desirable,

ver-arm will lie in the path thereof, and hence be raised when the rod reaches the required height. Ihe press will receive motion through belt H from the shaft upon which the fast and loose pulleys before mentioned are mounted, whereby, as soon as the belt has been shipped from the fast to the loose pulley through the agency of the aforesaid indicator-rod and my improved device, the operation of the machinery of the press will be stopped.

In Fig. 4 I have shown the lever having a portion of its long arm bent vertically, this form of lever being used Where a horizontal thrust of some portion of the machine with which my device is connected will be required to operare the shipper so as to 'cheek transmission of motion to said machine.

In conclusion, I may add that it is obvious that my device might be used in connection with a water-tank, devices Within the province of any mechanic being employed in lsuch connection to cause the operation ot the belt-op erating lever after the tank has been lled to a certain height, and to cut off the dow of liquid therein, or to cause the action of said lever after a certain quantity ot' liquid has been drawn from the tank, and then to close the cock; also, that the construction of beltshipper could be considerably changed from that shown and still be adapted to be operated by the means set forth.

As shown in Fig. 5, the pivoted lever may engage directly with the slide bar, thus dispensing with a locking-bolt. In some cases although I prefer the construction hereinbefore described.

Having thus described my invention, what I claim isl. The combination, with a machine requiring its motion to be checked at a given time,

of the sliding locking-bolt, the pivoted lever engaging` said bolt and having one arm arranged to be operated by the said machine, so as to draw the locking-bolt at the time required for stopping the machine, and the slidebar adapted to he engaged by said bolt, and arranged upon the disengagement of the bolt to cause the action of devices checking the transmission from the source of power to the machine that has operated said lever, substantially as described.

2. The combination, with abelt-shipper, of a machine arranged to be set in motion or stopped by the action of' the shipper, and a device for causing the shipper to automatically act to cause the stoppage of said machine, the same consisting of the slide-bar connected with the shipper-rope, the locking-bolt adapted to engage and hold said slide-bar, and the lever arranged to engage and slide the locking-bolt, substantially as described.

3. The combination, with the notched slidebar K, of the locking-bolt adapted to engage and lock said bar, the lever N, engaging said bolt, and apparatus for automatically actuating the long arm of said lever and causing it to disengage the locking bolt from the slidebar, substantially as described.

4. The combination, with a machine requiring` its motion to be checked at a given time, of the pivoted lever, with the sliding bar K, the said bar being adapted to be engaged by said lever, and being arranged so that upon the disengagement ot the lever therefrom the devices checking the transmission of power to the machine will be operated, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
